Death is only interesting if confronting it causes prime directive shift: how to survive?(which people recite subconciously on loop) changes to, why to survive?

Definitely not. I've learned to live comfortably with the fact that I'll die one day (and really understand/internalize it). Knowing exactly when could potentially disturb the peace that I've found.

You can use actuarial math and get pretty damned close. Like within five years with 80% confidence. Not as much romance in that as there is in a Time Machine.

No, not really. It sounds stressful.

Is the information actionable ?

I'd be shown myself being murdered by the operator of the time machine, after asking far too many questions about its theory of operation.

Nope
